Turning raw DMARC XML into decisions: aggregate report analysis
A DMARC aggregate report is one of the most useful documents your domain will ever generate, and one of the least read. Publish a record with a rua= tag and, within a day or two, gzip-compressed XML files start.

What DMARC reports do and do not tell you
Passing DMARC is permission to be judged on your merits, not a guaranteed seat in the inbox. Here is how to read aggregate reports for exactly what they measure, identity and authentication, without mistaking a perfect pass rate for good deliverability or panicking at failures that do not matter.

DMARC aggregate vs forensic reports
DMARC sends two kinds of feedback: aggregate (rua) reports and forensic (ruf) reports. They answer different questions and carry very different privacy risks. This guide explains exactly what each contains, why forensic reports have all but vanished, the data-protection considerations on both sides, and how to turn the aggregate data into a safe path from p=none to p=reject.

DMARC external destination verification
Sending DMARC reports to an address outside your own domain is an external destination, and RFC 7489 requires the receiving domain to authorise it first. Here is exactly which DNS record to publish, where, and why reports silently vanish without it.

DMARC reporting: mailto vs https URIs
The rua and ruf tags accept both mailto: and https: URIs, but almost every working DMARC record uses mailto: only. Here is why HTTPS delivery is dead in practice, how the size-limit suffix and external destination verification work, and how analysers ingest the gzipped XML.

What is TLS-RPT?
TLS-RPT (SMTP TLS Reporting) is a single safe-to-publish DNS record that gives you a daily, machine-readable summary of how other mail servers negotiated encryption with your inbound MX hosts. Learn what the record and its JSON reports contain, how to decode each failure type, and the exact publish-then-enforce workflow that pairs it with MTA-STS without risking an email outage.
